node.js - Gatsby 的环境变量 "env.cmd not found"

Question

尝试使用 Gatsby 运行 env.cmd，但我收到 sh: env-cmd not found。我确实已经安装了软件包。我尝试删除 .node-modules 并运行 npm install 但我仍然遇到同样的错误。

gatsby-config.js:

{
...
  "scripts": {
    "build": "gatsby build",
    "develop": "env-cmd --file .env.development --fallback gatsby develop",
    "format": "prettier --write \"**/*.{js,jsx,json,md}\"",
    "start": "npm run develop",
    "serve": "gatsby serve",
    "clean": "gatsby clean",
    "test": "echo \"Write tests! -> https://gatsby.dev/unit-testing\" && exit 1"
  },
  "dependencies": {
    "gatsby": "^2.18.12",
    "gatsby-plugin-sass": "^2.1.26",
    "node-sass": "^4.13.0",
    "react": "^16.12.0",
    "react-dom": "^16.12.0",
    "typescript": "^3.7.4"
  },
  "devDependencies": {
    "env-cmd": "^8.0.2",
    "prettier": "^1.19.1"
  },
...
}

终端:

npm run develop

> gatsby-starter-hello-world@0.1.0 develop /Users/renatognunes/Documents/Studies 1:4/Gatsby/gatsby-site
> env-cmd --file .env.development --fallback gatsby develop

sh: env-cmd: command not found
npm ERR! code ELIFECYCLE

npm ERR! gatsby-starter-hello-world@0.1.0 develop: `env-cmd --file .env.development --fallback gatsby develop`

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
